krek1111 [17]

First, let's declare a variable

x = # of students

Now, let's create an equation to model the problem.

x * 0.273 = 125

Divide both sides by 0.273

x = 457.8 = 458 students.

Note, I rounded to the nearest whole number.

A rectangle is placed around a semicircle as shown below. The width of the rectangle is 9 mm. Find the area of the shaded region

kogti [31]

Answer:

Step-by-step explanation:

So since 9 is your radius because this is half a circle you want to use the equation piR^2 which is pi9^2, by solving this equation you end up with 254.34, which is the area of the semi-circle, now you need to find the area of the box but to solve this you would need the length and width and multiply them together to get the area of the box then subtract that by the area of the semi-circle and you get the shaded region

A football team consists of 18 freshmen and 18 sophomores, 15 juniors, and 12 seniors. Four players are selected at random to se

Answer:

58.05% probability that at least 1 of the students is a senior.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the captains are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

Either no seniors are captain, or at least one is. The sum of these probabilities is 100%. The easier way to solve this question is finding the probability of no seniors being captain, and subtratcing 100 from this. So

Probability of no seniors being captain:

Desired outcomes:

Four captains, from a set of 18 + 18 + 15 = 51. So

$D = C_{51,4} = \frac{51!}{4!(51-4)!} = 249900$

Total outcomes:

Four captains from a set of 18 + 18 + 15 + 12 = 63. So

$T = C_{63,4} = \frac{63!}{4!(63-4)!} = 595665$

Probability:

$p = \frac{D}{T} = \frac{249900}{595665} = 0.4195$

41.95% probability of no seniors being captains.

Find the probability that at least 1 of the students is a senior.

p + 41.95 = 100

p = 58.05

58.05% probability that at least 1 of the students is a senior.
